Forced deep throat gagging

This drawing shows exactly why I was going to buy and what I was going to do with the Elypse Art canine dildos! The shaft should be long enough to penetrate the throat, and the (inflated) knot can be used as a ball gag. It must not be completely mouth filling to allow breathing around it.

Let me know if you have seen or know (or can think of) any other “devices” that can be used for deep throating.
